Located in a charming book-filled cottage, Krown & Spellman specializes in all manners of scholarly books printed from the 15th through the 17th centuries. It's by appointment only, and the Frank Spellman experience is worth making a date. He'll allow you to handle medieval hand-painted miniatures, or perhaps a 10th century Chinese scroll. There's a fascinating selection of occult books, with subjects like theosophy, slight-of-hand, or even darker realms. For the religious-minded, theology books abound about the Bible. There are 3,500 of the most rare books and manuscripts on hand, and 10,000 more in storage that are mostly sold over the Internet.
